The secretary of the Department of Transportation shall, not less than semi-annually, review the performance of each county's program of overweight vehicle enforcement and shall certify a list of those counties whose enforcement programs are unsatisfactory. In reviewing each county's enforcement program, the secretary shall consider the following factors:
The secretary may not find any county's program to be unsatisfactory unless the secretary has given the county a written specification of the county's program deficiencies at least thirty days before the unsatisfactory certification.
For any county whose overweight vehicle enforcement program is certified by the secretary as unsatisfactory, the secretary may withhold or suspend for a period of one hundred eighty days all or any portion of any transfer of federal surface transportation funds and state funds otherwise authorized by § 32-11-35 to be distributed to such county. The Department of Revenue shall cooperate with the secretary in the administration of this section.
